Potassium has several known isotopes, some of which are stable or at least very long lived. 19K is not one of hem. 32K (13 neutrons) to 55K (36 neutrons) have been identified. The stable ones are 39K and 41K. Should an isotope 19K be created, it would have no neutrons. It would decay by electron capture (most likely) to something like fluorine. With a great number of gamma photons emitted as well.
Isotopes of an element differ only in the number of neutrons. Oxygen has atomic number 8, meaning 8 protons. It has Atomic Mass 16, meaning 8 neutrons. In the O-19 isotope, the mass is now 19, meaning 11 neutrons (19 - 8).
Oxygen-19 has 10 neutrons. This can be calculated by subtracting the atomic number of oxygen (8) from its atomic mass (19).
You take 19 and subtract 8 (amt. of neutrons in a neutral atom of oxygen) and get 11, so 11 is your answer.
Number of neutrons = Mass number - atomic number = 39 - 19 = 20
10 neutrons
Argon has 22 neutrons.
Indium has 66 neutrons.
Number of neutrons is 48 (mass number) minus 21 (proton number) = 27 (neutron number)
Bi-211 (and all other Bi isotopes) has atom number 83, hence there are 83 protons.
There are varying isotopes of iodine, but typically an iodine atom has 74 neutrons.
Fluorine
How many neutrons would it have if it had 11 neutrons? 11.
18 neutrons
Palladium has 60 neutrons. It has an atomic number of 46, which means it has 46 protons. To find the number of neutrons, you subtract the atomic number (protons) from the atomic mass (protons + neutrons). Palladium's atomic mass is approximately 106.4, so 106.4 - 46 = 60 neutrons.
